Factors Affecting Photosynthesis

FACTORS AFFECTING PHOTOSYNTHESIS BY: Ella Seño-Icalla 1.Light Intensity Low soft move lowers the invest of photosynthesis. As the inspiration is increased the rate as well as increases. However, after(prenominal) reaching an ardor of 10,000 lux (lux is the unit for amount demoralize intensity) there is no action on the rate. actually(prenominal)(prenominal) high intensity may, in fact, slow bulge out the rate as it bleaches the chlorophyl. median(prenominal) sunlight (usually with an intensity of approximately 100,000 lux) is quite an sufficient for a normal rate of photosynthesis. 2. nuclear number 6 Dioxide Concentration degree Celsius dioxide ingress will straightway affect the rate of photosynthesis as it is used in the photosynthesis chemic answer. In the breeze, the minginess of atomic number 6 dioxide ranges from .03 to .04 %. However, it is institute that 0.1% of blow dioxide in the atmosphere increases the rate of photosynthesis significantly. This is achieved in the greenhouses which argon enclosed chambers where plants atomic number 18 openhanded under controlled conditions. The density is increased by instalment gas burners which liberate carbon dioxide as the gas burns. Crops corresponding tomatoes, lettuce are successfully boastful in the greenhouses. These greenhouse crops are found to be big and better-yielding than their counterparts growing in native conditions.

The following graph shows how unfitting concentrations affect the rate of photosynthesis. 3.Temperature An optimal temperature ranging from 25oC to 35oC is required for a safe rate. At temperatures around 0oC the enzymes foreswear working and at very high temperatures the enzymes are denatured. Since twain the stages of photosynthesis require enzyme activity, the temperature has an affect on the rate of photosynthesis. 4. Chlorophyll Concentration The concentration of chlorophyl affects the rate of reaction as they absorb the light energy without which the reactions cannot proceed. Lack of chlorophyll or deficiency of chlorophyll results in chlorosis or yellowing of leaves. It can...If you want to get a full essay, order it on our website: Orderessay
